It’s not your imagination: your Mac’s overall performance can slow down over time. Most often this happens because we gradually add more apps and background processes, have more and more documents and browser tabs open, and don’t restart very often. All these things take a cumulative toll on your Mac’s performance. Cutting back on the number of things you have open is therefore one of the easiest strategies for putting some zip back into your Mac. Adding RAM (if your Mac supports it), switching from a hard drive to an SSD, and keeping your software up to date are also effective quick fixes for performance problems.​

Wait, what?? Mac performance slows if:

you run more programs and load more startup/background processes

You open more documents and browser tabs

Don't Restart very often - What??? Restart a Mac, never!

You don't update software

You use an old slow HDD vs an SSD

Run with the stock level of ram

Who knew? - You probably don't want to know if you're swallowing that "It just works" meme.

Yes Francis, All computers suffer these maladies you're not so special.
